Meaning the official Warhammer 40K RTS with the actual Warhammer 40K license. The version I'm giving this a rating is not the bugfest that is the vanilla one - the one with the honour of introducing me to my current favourite faction of the IP, the adepta sororitas, as well as the dark eldars - which I didn't really play that much back in the day since I became bored pretty quickly with it but to the version with the Unification Mod added, which adds a lot of content to the base game for all factions that makes it updated to the current Warhammer 40K Lore (for example, amongst the soulstorm mods it's the only one with the amazing looking Paragon Warsuit and Canoness Morgenn Vahl in it) and, with the unification campaign extended mod, it even throws the possibility of playing new factions in the conquest of the Kaurava system like Tyranids, two branchs of the Inquisition, Chaos Deamons etc. Etc. Good stuff that it just feels good to do, even if there are some minor setbacks and in particular the fact that the fortresses of the new factions are limited to boring defense missions against waves of enemies which are a bit nonsensical IMHO (I'm not a fan of defense missions in RTS unfortunately). For the rest, I have nothing bad to say to the unification mod, all the contrary it elevates the base experience - which, to be honest, was clearly done by people with zero knowledge about the Warhammer 40K lore in a rushed way to capitalize on the good reputation Dark Crusade gained amongst the RTS fans, me included - to a really enjoyable thing overall. I can't wait for the upcoming release of version 7.0 to see what the unification mod has in mind!
Oh and I don't care what the naysayers say, the cover art of the DVD of this game - the last Dawn of War iteration ever produced to my knowledge - is supercool. Adepta Sororitas on a purple background = instant love.
